Hello. I just had a question with regards to a problem I am having with my USB devices.I was wondering if anyone would be able to help me with my current problem. So my situation is that every time I plug in a new device in the USB port, it installs the device, but the device does not work. An example is a new mouse that I bought. When I plugged it in my computer, it installed it properly, and the mouse's optical light lights up. However, the cursor does not work. I tried using the mouse on two other computers, and it works fine. I have had this problem for a couple of months now. Some of my older USB devices that I've installed a longer time ago still work. I have a mouse (that I actually broke, hence the new mouse) that still works. I can also still update my phone using an old USB cable that I had; however, the newer cables to not seem to work. I also still have an older USB charger that still works fine as well. This has me wondering what the problem really is. I have tried a couple of things: -I have tried uninstalling and reinstalling the USB Root Hub in the device manager, but it still fails. -I have tried doing system restore, but it did not do anything either. -I also tried using the mouse in Safe Mode, but it does not work there either. I don't know whether or not it is related to my other problem, which is that Vista does not update properly. When I try to shut down my computer, it says it is "installing updates 1 out of 3," but it says it fails and it does not install properly. So I was wondering if you had any suggestions on how to fix this? Thank you in advance!
